From cc2d22477779f189595db5c515bd5ef9c75a1f35 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Mon, 7 Jan 2019 20:49:39 +0100 Subject: [PATCH] pwm: Drop per-chip dbg_show callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This callback was introduced in commit 62099abf67a2 ("pwm: Add debugfs interface") in 2012 and up to now there is not a single user. So drop this unused code.
